In our study, although the lymphocyte count decreased in patients with AIS, the reduced ratio of CD45RA+CCR7+ (naïve) T cells, and increased ratio of CD45RO+CCR7+ T (Tcm) and CD45+CCR7− T (Tem) cells, further confirmed that the adaptive immune response could be rapidly stimulated in patients with LVO by stimulating the transformation of T cells into memory T cells. This evidence concerns the gene PTPRC and androgen insensitivity syndrome.
